PRINTING AND EJECTHNG MECHANISM FOR CASH REGISTERS Application March 7,

1934, Serial No. 714,478

in Germany March 13, 1933 10 Claims.

This invention relates to improvements in the type of cash registeroften referred to as an` accounting machine or posting machine andillustrated and described in Letters Patent of the United States No.1,747,397, issued February 18,

1930, to B. M. Shipley.

Generally speaking, it is an object of this invention to provide anaccounting machine with means to positively eject record material, saidejecting means also serving as a means for locating record material inrelation to the printing mechanism.

A more specific object is to provide the machine of this invention with.a reciprocating ejecting bar that extends the full width of the typecarriers and impression mechanism and travels across the printing pointto positively remove insertable slips from between the type carriers andthe impression mechanism.

Another object is to supply novel means to align the edge of theinsertable siip with the locating ejecting member.

With these and incidental objects in view, the invention consists ci'certain novel features of construction and combinations of parts, theessential elements of which are set forth in appended claims and apreferred form or embodiment of which is hereinafter described withreference to the drawing which accompanies and forms a part of thisspeciiication.

Of said drawing:

Fig. l is a front elevation showing the mechanism of this invention.

Fig. 2 is a plan View as observed from above illustrating a portion ofthe impression and ejecting mechanisms.

General description 40 The impression hammer of the instant machine isactuated twice in each machine operation to first print various amountsand data upon an insertable record slip and then to duplicate thisimpression upon an audit strip which is rcv tained in the machine. Theweb of the audit strip is unwound from the receiving roll and threadedaround various guide rolls past the platen of the impression hammer,thence around the impression hammer, after which it is wound 510 upon areceiving roll in the well known manner.

" A reversible inking ribbon passes between the web of the .audit stripand the type carriers.

Prior to releasing the machine for operation,

the record slip is inserted between the inking vrp ribbon and the web ofthe audit strip, which it will be recalled are interposed between theimpression hammer and the type carriers. During machine operationinitial movement of the impression hammer forces the record slip and theinking ribbon into contact with the type carriers to cause animpressionto be made on said record slip. Immediately thereafter the record slipis ejected from the machine and the second movement of the impressionhammer moves the audit strip into Contact with the inking ribbon and thetype carriers to cause a duplicate impression to be made upon said auditstrip.

n The usual slip ejecting mechanism consists of pairs of superimposedrollers or disks between which at the proper time the slip is grippedafter which rotation of the rollers ejects the slip. With this type ofejecting mechanism the accidental or intentional insertion of a slipwhich covers the printing point but which is not wide enough to engagethe ejecting rolls, would, upon machine operation, result in such a slipnot being ejected after the first impression. Consequently the secondimpression would also be made upon the record slip thereby preventing arecord of the transaction being imprinted upon the audit strip. It isvery necessary that a duplicate record of all transactions be kept uponthe audit strip, as this record is very important to the proprietor of abusiness establishment in checking the business over a certain period.

In order to prevent unscrupulous employees from inserting narrow stripsof paper between the type carriers and the impression mechanism, therebydestroying the proprietors record, the instant novel ejecting mechanismwas devised. This mechanism consists of a reciprocating bar which passesbetween the impression hammers and the type carriers immediately afterthe rst impression is made, and positively removes or ejects anymaterial, regardless oi size, away from the printing point. This insuresa recording of the transaction on the audit strip. The mechanism of thisinvention will now be described in detail.

Detailed description Calling attention to Figs. i and 2, transversingthe machine from front to rear and journaled in a bracket secured to themachine base and the printer front and back frames is a printer y to anarm 31 secured on a shaft 3S, the forward plate 4B.

Secured on opposite ends of the shaft 38 are arms 4l and 42 havingpivoted thereto, respectively, the left ends of symmetrical links 43 and44. The right hand ends of the links 43 and 44, respectively, fitloosely on studs 45 and 46 secured in upturned ears 4'! and 49 of a sliplocating and ejecting bar 49. The ears 4l and 48 of the bar 49 have inthe inner surfaces thereof, parallel grooves 55 and 5l, which cooperaterespectively with parallel rails 52 and 53 Aformed respectively onstationary and similar plates 39 and 54. Y

Pivoted at 55 is an impression hammer 56 with a platen 57 which isadapted to be rocked clockwise into contact with type carriers 53 looseon a rod 59 supported by the printer frames. EX- tending above the typecarriers 58 is aslip table 60 having an opening il through which-theimpression hammer d passes to Contact the type carriers 58. Theimpression hammer 55 is enclosed by a case 62, the right hand end ofwhich is narrowed down and in cooperation with the slip table 69 forms aslip chute63 for guiding record material between the impression meansand the type carriers. strip 64 is visible through a glass window G5 inthe case 62.

From the supply roll the web of the audit strip 64 is threaded aroundthe pivot point 55, thence around the guide roll 66 across the face or"the platen 5l, around a guide roll 6l, around the edge of a writingtable $8 secured to the impression hammer 5l' and then wound upon areceiving roll (not shown). Opposite ends of the guide roll 6B arejournaled in arms 69 and 19 secured on a shaft 'll rotatably supportedby the plates 39 and 54. An extension 'i2 of the arm 19 is bent atright-angles to cooperate with a flat spring 'i3 secured to theimpression hammer 56. The spring T3 urges the arm 'l0 clockwise, asviewed. in Fig. l, into engagement with a stop stud 14 secured in theimpression hammer 55.

' The arm 'i3 by means of the shaft Il and the arm 69, urges the roller68 clockwise, causing said roller and the audit strip t4 to yieldinglyengage the upper edge of the ejecting bar 49. An inking ribbon passesaround a guide roller 1.6, thence above the type carriers 58, and arounda spring member 1l' secured to a guide plate lli.' The spring member iltogether with the ink ribbon 15 yieldingly engages the lower edge of theejecting bar 49.

In use, the record slip is inserted Within the chute 63 and advanceduntil the edge thereof, guided by the roller 55 and the spring member'Vl engages a V-shaped groove 'i9 in the right hand edge of the ejectingbar 49. This locates the record slip in relation to the printingmechanism. The first movement of the impression v hammer 235 forces therecord slip, together with the ink ribbon 15, into contact with the'typecarriers 58 to impress a record on said slip.

Immediately after this first impression is taken the groove 32 in thecam 3l in cooperation with the roller 33 rocks the bell crank 34, firstin a clockwise direction, which by means of the link 35 also rocks thearm 3?, the shaft 38, and the arms 4l and 42 in a clockwise direction.Clockwise movement of the arms 4l and 42 by means of the links 43 and 44moves the ejecting bar 49 horizontally toward the right, in whichmovement it is guided by means of the rails 52 and 53, in cooperationwith the parallel slots in the The printing on an audit end ofl which isjournaled in a printer front upturned ears of said ejlecting bar 49.This ini-f tial movement of the ejecting bar 49 positively ejects anyrecord material, regardless of its length, from between the impressionhammer 56 and the type carriers 58.

Before the second impression is made` the cam 3| returns the ejectingbar 49 to normal position, as shown in Fig. 1. Immediately thereafterthe impression hammer 56 isagain moved downwardly to carry the auditstrip 64 and the ink ribbon 15 intoncontact with the type carriers 58 toprint a duplicate record upon said audit strip 64.

The upper end of the extension 12 of the arm 10 forms a convenientfingerpiece 8U by which the shaft 'll and the guide roller 65 may berocked counterclockwise if. necessary to assist in properly insertingand locating record material within the machine.
